				<content:encoded><![CDATA[<p>BBR相关介绍可以看:<br />

<a href="http://blog.it580.com/?feed-stats-url=aHR0cHM6Ly93d3cuemhpaHUuY29tL3F1ZXN0aW9uLzUzNTU5NDMz&#038;feed-stats-url-post-id=2613" target="_blank">知乎: Linux Kernel 4.9 中的 BBR 算法与之前的 TCP 拥塞控制相比有什么优势？</a></p>
<p>VPS现有情况: Debian Jessie, Linode 2048.</p>
<p>实作如下:</p>
<p>1、将版本从Jessie切换到testing</p>
<blockquote><p>nano /etc/apt/sources.list</p></blockquote>
<p>替换所有jessie 为 testing ，保存修改。</p>
<blockquote><p>apt-get update<br />
apt-get -u -o APT::Force-LoopBreak=1 dist-upgrade<br />
apt-get autoremove</p></blockquote>
<p>更新到testing版本</p>
<p>2、安装新内核</p>
<blockquote><p>apt-get install <span class="s1">linux-image-4.9.0-1-686-pae</span></p></blockquote>
<p>安装完重启后，可以用uname -a 确认。</p>
<p>3、开启bbr</p>
<blockquote><p>echo &#8220;net.core.default_qdisc=fq&#8221; &gt;&gt; /etc/sysctl.conf<br />
echo &#8220;net.ipv4.tcp_congestion_control=bbr&#8221; &gt;&gt; /etc/sysctl.conf<br />
sysctl -p</p></blockquote>
<p>4、验证确认</p>
<blockquote><p>sysctl net.ipv4.tcp_available_congestion_control<br />
sysctl net.ipv4.tcp_congestion_control</p></blockquote>
<p>如果都发现了bbr，开启成功。</p>

				<content:encoded><![CDATA[<p>1、shadowsocks安装</p>
<blockquote><p>opkg update &amp;&amp; opkg install <span class="s1">shadowsocks-libev</span></p></blockquote>
<p>2、shadowsocks配置</p>
<blockquote><p>vi /etc/shadowsocks-libev.json  #根据服务器信息配置</p>
<p>vi /etc/init.d/shadowsocks-libev #修改CONFIG_FILE=/etc/shadowsocks-libev.json</p></blockquote>
<p>3、<span class="s1">dnsmasq配置</span></p>
<blockquote><p>vi /etc/dnsmasq.conf   #在文件末加入 server=127.0.0.1#5300</p></blockquote>
<p>4、启动相关服务</p>
<blockquote><p>/etc/init.d/shadowsocks-libev enable<br />
/etc/init.d/shadowsocks-libev restart #如果未启动，改为start<br />
/etc/init.d/dnsmasq restart</p></blockquote>
<p>完成这四步路由器已经实现完全翻墙，如果需要实现国内域名的本地解析继续往下看。</p>
<p>5、chinese list</p>
<p>网址: <a href="http://blog.it580.com/?feed-stats-url=aHR0cHM6Ly9naXRodWIuY29tL2ZlbGl4b25tYXJzL2Ruc21hc3EtY2hpbmEtbGlzdA%3D%3D&#038;feed-stats-url-post-id=2610">https://github.com/felixonmars/dnsmasq-china-list</a></p>
<blockquote><p>mkdir /etc/dnsmasq.d/<br />
cd /etc/dnsmasq.d/<br />
wget https://github.com/felixonmars/dnsmasq-china-list/raw/master/accelerated-domains.china.conf<br />
vi /etc/dnsmasq.conf #在末行加入conf-dir=/etc/dnsmasq.d</p></blockquote>
<p>重新执行第4步，并使用国内视频网址验证访问国内地址是否正常。</p>
<p>如果一起正常，完成。</p>

				<content:encoded><![CDATA[<p>好久没有更新路由器的版本，新年正好更新下。</p>
<h2>1、检查现有版本</h2>
<blockquote><p>cat /etc/banner  #查询现有版本编号</p></blockquote>
<p>DESIGNATED DRIVER (Bleeding Edge, <strong>xxxxx</strong>)  &#8212; 我用的是snapshots版本，<strong>xxxxx</strong>为详细版本号</p>
<blockquote><p>cat /proc/cpuinfo  #如果懒得去看路由器，可以直接查询硬件型号</p></blockquote>
<p>system type : Atheros AR7161 rev 2<br />
machine : NETGEAR WNDR3700/WNDR3800/WNDRMAC</p>
<p>和官网wiki信息对比: <a href="http://blog.it580.com/?feed-stats-url=aHR0cHM6Ly93aWtpLm9wZW53cnQub3JnL3RvaC9uZXRnZWFyL3duZHIzNzAw&#038;feed-stats-url-post-id=2608">https://wiki.openwrt.org/toh/netgear/wndr3700</a> , 只有v1，v2两个型号。(差别是flash，直接用df命令进行比对，确认为v2版本)</p>
<h2>2、下载对应版本及更新</h2>
<p>去官网检索对应的固件，ar71xx系列地址: <a href="http://blog.it580.com/?feed-stats-url=aHR0cDovL2Rvd25sb2Fkcy5vcGVud3J0Lm9yZy9zbmFwc2hvdHMvdHJ1bmsvYXI3MXh4L2dlbmVyaWMv&#038;feed-stats-url-post-id=2608">http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/</a></p>
<blockquote><p>cd /tmp<br />
#下载固件文件<br />
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/openwrt-ar71xx-generic-wndr3700v2-squashfs-sysupgrade.bin<br />
#下载md5校验文件<br />
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/md5sums<br />
#md5校验<br />
md5sum -c md5sums 2&gt; /dev/null | grep OK</p></blockquote>
<p>确认文件下载正常就可以刷入固件，因为3700v2的空间和内存足够，直接刷入。(建议使用有线状态刷入)</p>
<blockquote><p>sysupgrade -v /tmp/openwrt-ar71xx-generic-wndr3700v2-squashfs-sysupgrade.bin</p></blockquote>
<h2>3、更新确认</h2>
<blockquote><p>cat /mnt/banner</p></blockquote>

				<content:encoded><![CDATA[<p>Debian 7 Stable资源库当前MySQL Server是5.5,常出问题的5.5&#8230;&#8230;</p>
<p>推荐使用MySQL的<a title="MySQL的官方APT资源库" href="http://blog.it580.com/?feed-stats-url=aHR0cDovL2Rldi5teXNxbC5jb20vZG93bmxvYWRzL3JlcG8vYXB0Lw%3D%3D&#038;feed-stats-url-post-id=2581" target="_blank">官方APT</a>进行安装，更换为5.6 &#8211; 5.7。示例如下:</p>
<blockquote><p>wget http://dev.mysql.com/get/mysql-apt-config_0.3.2-1debian7_all.deb<br />
dpkg -i mysql-apt-config_0.3.2-1debian7_all.deb<br />

<p>建议各位先不要使用该版本，中文版强行捆绑的太极应用，cydia作者的twitter(他都不知道捆绑的是什么版本的cyida)，之前传说的越狱程序被盗事件。</p>
<p>以防万一，还是等事情水落石出再越狱吧。</p>

<p>为防止信用卡被盗刷，请自行关闭或取消国际支付功能，联系信用卡发卡行要求更换新卡(告知信用卡卡号、到期时间、CVV泄露)，某些银行可能要求你采用挂失方式。</p>
